January and February are the two months Americans most want to leave and the two months it costs the most to do it badly. The good news is that warm winter vacations in the USA do not need a passport, a long-haul flight or a peak-season resort — four states and one territory stay properly warm all winter.
The split is simple: Florida and Puerto Rico for heat and water, Southern California and Arizona for dry warmth and hiking, Hawaii for the version worth the flight. Each has a very different price and a very different January.
Here is where actually stays warm, what each place costs in high season, and what to book.

Puerto Rico: the Best Value Warm Winter
San Juan in January is 27°C, takes US dollars, needs no passport for Americans, and costs about half what Hawaii does. It is comfortably the best-value warm winter trip in the country and most people never consider it.
El Yunque is the only tropical rainforest in the US National Forest system — waterfalls, natural waterslides and a rainforest hike, an hour from the city. And the catamaran day out to the Cordillera islands from Fajardo gets you to water that looks like the Caribbean because it is.
Florida: Miami, the Keys and St Augustine
Miami in winter is the driest, most pleasant version of itself — 22°C, low humidity, and the water still swimmable. An open-top bus and Biscayne Bay cruise combo is the efficient first day if you have never been.
Key West is four hours further south and four degrees warmer, and it is the one place in the continental US that genuinely feels tropical in February. A sunset sail on the schooner America 2.0 is the thing to do the first evening — the sunset is a civic event here.
St Augustine is the northern Florida option and the oldest continuously occupied European settlement in the country — a Spanish colonial old town, a 17th-century stone fort, and 20°C in January without the South Florida prices. The trolley and history museum ticket or the tour pass covering 30-plus attractions both make sense here because the sights are spread out.
New Orleans: Warm, Cheap and at Its Best
Winter is quietly the right time for New Orleans. It is 17–20°C, the summer humidity is gone, hotel rates drop between New Year and Mardi Gras, and the city is doing its own thing rather than performing for a convention.
Three things worth booking: a French Quarter food and history walk, the ghost, voodoo and vampire walking tour after dark, and an evening steamboat jazz cruise on the Mississippi — which is the one that surprises people.
One warning: rates jump hard for Mardi Gras and the two weeks before it. If you want cheap New Orleans, come in January.
The Dry West: Palm Springs, Sedona and the Central Coast
If you want warmth without humidity, the desert delivers. Palm Springs runs 20–24°C days in January with mid-century architecture, hot springs and a mountain tram that climbs from desert to pine forest in ten minutes. Sedona is cooler, at 18°C, and the red rock hiking in winter is far better than in a 40°C summer.
Both come with a caveat: the nights are cold. Palm Springs drops to about 7°C after dark and Sedona to near freezing, so pack a proper jacket even though the days are shorts weather.
For something softer, a three-winery tour with a picnic lunch in Paso Robles on California’s central coast is 18°C, green in winter, and a fraction of Napa’s prices.
🐧 BuKoo Tip: The desert is a two-wardrobe trip. Palm Springs and Sedona swing 15°C or more between afternoon and night — shorts at two, a warm jacket at six. People consistently under-pack for this and end up buying a fleece at the trailhead gift shop. Bring layers and a proper jacket even though the forecast says 22°C.
Hawaii: Whale Season
Winter is not the off-season in Hawaii — it is humpback season. Thousands of whales come down from Alaska to calve in the shallow channels between Maui, Lanai and Molokai from December to April, and they are close enough to see from the beach.
A Maui whale-watching cruise with a marine naturalist is worth the extra over the cheap boats — the commentary is the difference between seeing a splash and understanding what you are watching. Waikiki runs its own season if you are based on Oahu.
The other Maui thing is the Haleakala sunrise — above the clouds at 3,055 m, and genuinely cold up there, around 3°C before dawn. Reservations are required and they open 60 days ahead.
On Kauai, winter is the wet season on the north shore and that is exactly why the waterfalls run. A Waimea Canyon and Jurassic Falls helicopter tour is the splurge that people say was the best hour of the trip; a fixed-wing sightseeing flight does most of it for much less.

⭐ BuKoo Quick Picks
💸 Best value: Puerto Rico. Warmest of the lot, no passport, and roughly half what Hawaii costs.
🐋 Best once-a-year thing: humpback season off Maui — December to April only, and worth planning the whole trip around.
🌅 Best cheap evening: the Key West sunset sail. Two hours, and the whole town stops for it anyway.
🥾 Best for hikers: Sedona in January — the red rock at 18°C instead of 40°C, and no crowds on the trails.
Good to Bring
Two very different packing lists here: humid and coastal for Florida, Puerto Rico and Hawaii; dry and swinging fifteen degrees a day for the desert.
🧴 A reef-safe mineral sunscreen stick — Hawaii bans oxybenzone sunscreens outright and Key West asks you not to use them.
👟 Quick-dry water shoes — for El Yunque’s waterslides, coral beaches and boat ladders.
🤿 Your own snorkel set — rental gear on catamaran day trips is the worst part of an otherwise good day.
🧥 A packable rain shell — Kauai in winter is the wet season, which is why the waterfalls are running.
🔦 A rechargeable headlamp — for the Haleakala pre-dawn drive, and any early trailhead start in Sedona.
Where to Stay
San Juan and Key West are the two bases that need booking earliest — San Juan because it is the best value and word is spreading, Key West because it is a small island in peak season. Hawaii needs three to four months for February.
Warm Winter Vacations: Your Questions Answered
Where is the warmest place in the USA in winter?
Puerto Rico, at about 27°C in January, then Hawaii and Key West at 24–26°C. On the mainland, South Florida and the southern tip of Texas are the only places reliably above 20°C.
When is the cheapest time for a warm winter trip?
Early January, right after the holidays and before the February peak. Florida and Hawaii are at their most expensive in February and over Presidents’ Day; New Orleans is cheapest in January and dearest at Mardi Gras.
Is it warm enough to swim in Florida in winter?
In South Florida and the Keys, yes — sea temperatures sit around 22–24°C. North Florida, including St Augustine, is pleasant to walk in but too cold for most people to swim.
Do you need a passport for Puerto Rico?
Not if you are a US citizen — it is a US territory, uses the dollar, and domestic flights go there. That is a large part of why it is the best-value warm winter trip in the country.
When is whale season in Hawaii?
Humpbacks are in Hawaiian waters from roughly December to April, peaking in January and February. The channel between Maui, Lanai and Molokai is the best place to see them, from a boat or from the shore.
